How is the second cell cycle checkpoint (after G2) different than the first?
A. The size of the cell is checked to make sure it is large enough to proceed.
B. The DNA is checked to make sure it is fully replicated.
C. The DNA is checked to make sure it is intact.
D. The nutrient supply is checked to make sure it is adequate.
C. The DNA is checked to make sure it is intact.
The second cell cycle checkpoint, also known as the G2/M checkpoint, ensures that the DNA is fully replicated and undamaged before the cell proceeds to mitosis. This checkpoint helps prevent the transmission of mutations or DNA damage to daughter cells during cell division.
